46 wardly FUNITED STATES To all whom it may concern:

Be it known that I, Wxamon W. S' rA-i-IF'- FER, citizen of the United States, residing at Nappanee, in the county of Elkhart and State of Indiana, have invented certam new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to hand 0 erated wheeled cultivators, and has for its set to provide an improved device of the kind, characterized particularly by so arateframes at right and left hand, each o which carries a blade and a cultivating or mulching wheel.

- The construction is such that either set of implements and the frame which carries the same ma be lifted out of action independentl of t e other.

T e invention is illustrated in the accompanying drawings in which Figure 1 is a perspective view of the mplement. Fig, 21s a'front elevation. Figs/3, 4' and 5 are details. Referring specifically to the drawings, 6 m dicates an arched axle of sufficient hei ht to ass over ordinary plants or vegetables ound in gardens or the like.

The wheel hub and said sleeve are held between collars 10 on the straight ends of the axle, these collars bein fixed at adjustment h set screws, whic allows the arms and the wheels to be ad- 85 justed in or out on the axle, according to the width of the rows to be worked. One sleeve is fixed to the axle by a set screw 40. his

The bolt extends infrom the end of the arm, so as to bring thehan'dle in line behind the supporting wheel 7, the spread arms 12 being fixed at heir u per ends to the lower end of the han- 'd1e an at their lower ends to opposite ends of "the bolt 13'. The sleeve 14 is located between the lower ends of the arms and upon 'the bolt 13, and serves to space the arms apart, and also to support the cultivating. wheel to be described. The contacting sides it of the bearing atthe end of the arm 8, and

the corresponding side of the arm 12, are cor- Specification of Letters Patent. I Application-filed November 82, 1907. Serial No. 108,868.

rugated as at 15, to allow the handles to be set at any desired hei ht or angle, which can he done by loosening t e nuts on the bolts 13, and then adjusting the handleson the bolts 13 aspivots.

Each bolt 13'- carries or supports a wheel 16 which has aseries. of transverse blades or cutters- 17 pro-eating outwardly around its edge. These b ades are set at an angle to the axis and are intended to cut into the round a and to break u the crust or surface t iereof.

Behind each 0 the wheels is a weeding and cultivatin blade 18 which extends at a slight inclination across the line of motion and serves to out under the surface of the ground and so act as a weeder and also, if desired, to ridge or hill-up the soil alon the row.

The inner end of the knife is or may be turned up as indicated at 19. This knife is held by a clip 20 which engages the shank 21 of the knife. The shank extends through a vertical recess or bore in the clip or coupling,

and the clip is mounted on a cross bolt 22 which extends between the arms 12 and through a horizontal Set screws 23 enga ing the shank and the bolt respectivel al ow various adjustments to be made. hus the shank of the knife may be moved up or down to raise or lower in its socket, to vary the angle of the knife. also be turned on the bolt 23 to va the angle of the shank and the cut of the kni e, and furthermore may be moved lengthwise along sald bolt to vary the lateral osition of the knife and so set the knives c oser' together or farther apart, according to the 'cro being worked.

he wheels 16 consist of disks having lugs 24 on opposite sides of their edges, with a cross slit set in these slits and are astened by bolts 25. The action of the arms 8 and the handles on opposite sides of the axle is independent, so that the handle and devices on one side can be swun up or-lifted out of action indegendentlyo ependently operated by hands of the gardener.

When at work, the wheels of the blades cut up or disintegrate the ground and either loosen orcut the-weeds so that the surface blades 18,. following, will effectively cut out the grass and weeds, and also hill up the row if the knives are set for that purpose. The

The rotary knives are so constructed that they will not readily choke, and it is to be noticed that the shank of the stationary knife is connected thereto at or about the middle thereof, so that the ends are open and grass or weeds will clear away therefrom with out clogging.
